- the charging system shown in FIG. 1 has an external transmission part 10 and one implantable receiving part 11.
- a loading head 12 belongs to the external transmission part 10.
- the loading head 12 there is a transmission-side series resonance circuit 13 with a coil 14 and one in series therewith switched capacitor 15 housed.
- the coil 14 of the series resonant circuit 13 also forms the transmitter coil of the transmitter part 10.
